Biomass pellet fuel consists of straw, straw, rice husk, peanut shell, corn cob, camellia shell, cottonseed hull, etc., and three new materials are processed to produce clean, low-carbon renewable energy instead of conventional energy. Energy, high quality and environmentally friendly fuel. It can be used in high temperature hot water for textile, printing and dyeing, paper, food, rubber, plastic, chemical, pharmaceutical and other industrial products. The biomass pellet fuel has high calorific value, low sulfur content and low ash. Characteristics, the use of biomass pellet fuel is becoming more and more extensive. It is imperative to test the quality of biomass pellet fuel. What equipment is there for biomass pellet fuel heating quantitative inspection? This article is from Hebi Dingcheng Thermal Analysis Instrument Co., Ltd. Explain in detail what equipment is available for the biomass pellet fuel heating quantitative inspection machine.
First, biomass pellet fuel special calorimeter
The sulphur content of biomass pellet fuel is the determinant of its quality. Therefore, the equipment for testing the calorific value of pellet fuel is a necessary equipment for the detection of particulate fuel. Now the general calorimeter is based on the national standard "calcium calorimetric detection". Designed, can not adapt to the characteristics of biomass pellet fuel itself, the error is large, the result is unstable. Hebi Dingcheng Thermal Analysis Instrument Co., Ltd. keeps pace with the times, designed and produced DCLRY-9000 microcomputer with the characteristics of biomass pellet fuel Granular special calorimeter. Also called: particle detector for detecting biomass, biomass card machine, testing straw card machine, testing wood particle card equipment, detecting sawdust block card, coal gangue card test Instrument, test brick blank card tester, test brick blank heat card equipment, coal quality card number test machine, measurement biomass heat equipment, biomass heat test instrument, equipment for testing solid particle calorific value
The steps to use are:
1. Double-click to open the biomass particle special calorimeter program and turn on the power switch.
2. Calibrate the heat capacity of the biomass pellet calorimeter with benzoic acid.
3, using benzoic acid as a calorific value, see if the calorific value of the benzoic acid cartridge is close to 26,470 joules, the error is within plus or minus 20 joules, indicating that the equipment is normal, otherwise the biomass pellet calorimeter should be recalibrated.
4, weigh 1 gram of particulate fuel sample, accurate to one ten thousandth of a gram,
5, put the pellet fuel sample into the oxygen bomb,
6. Place the oxygen bomb filled with oxygen into the inner barrel of the biomass pellet calorimeter, and click the 'heating' button on the operation program interface. Start the test.
7, about 15 minutes or so, the biomass particle calorimeter printer automatically prints the results.
Second, biomass pellet fuel sulfur analyzer
The high sulfur content of biomass pellet fuel is one of the important indicators to determine its quality. The current sulfur analyzer is generally a Coulometric titration sulfur analyzer, and the DCCLY-8 fast particle sulfur analyzer consists of the following components: , high temperature cracking furnace: 2, sample feeding mechanism: 3, electrolytic cell 4, magnetic stirrer 5, air purification system 6, control system, control system is the core of sulfur analyzer, it is also the decision part of the performance of sulfur analyzer. The working principle is as follows: The particulate fuel is burned in the purified air stream under the high temperature condition of 1050 ° C and the catalyst, and various forms of sulfur in the coal are burned and decomposed into SO. 2And a small amount of SO 3Gas, and the purified air stream is brought into the electrolytic cell to generate H 2SO 3Or a small amount of H 2SO 4, H2SO 3I was immediately taken into the electrolyte 2(Br 2) oxidized to H 2SO 4, the result I in the solution 2(Br 2) decrease and I (Br) increase, destroying the equilibrium state of the electrolyte, indicating the potential rise between the electrodes, the instrument automatically judges the start of electrolysis, and according to the potential level on the indicator electrode, controls the magnitude of the electrolysis current corresponding thereto. Time, the I generated on the electrolysis electrode 2(Br 2) and H 2SO 3The amount of reaction consumed is equal, so that the electrolyte is returned to equilibrium, and the process is repeated until the end of the test. Finally, the instrument generates I based on the electrolysis. 2(Br 2The integral of the electricity consumption, and then calculate the total sulfur content in the sample according to Faraday's law of electrolysis.
Third, supporting equipment
Biomass pellet fuel heating quantitative inspection equipment is: '1' electronic balance: used to weigh the sample weight of one ten thousandth of the electronic balance, is the premise of accurate test results '2' blast drying oven: 5-200 ° C The blast drying oven is used to test the particulate fuel moisture, drying articles, drying heat treatment and other heating. '3' sealed test sample pulverizer: can quickly make pellet fuel in 3-5 minutes 80-200 mesh micronized sample.
